what is the crossover slope for the subwoofer cutoff frequency? 24 dB/octave, 12 dB/octave, 6dB/octave?

I am sorry but i am unable to answer your question about sub woofer x-over as i am not useing any subs my tasterun to smooth jazz and classical, subs do not go well with this kind of music.Add to that i am not useing the JVC to set my frequency's i am useing a 7 channel Clarion graphic band eq.$50.00 on amazon much easier to use to adjust as your driving and music changes.

The slope is not specified, either in the owner's manual or the online specifications. There are high-pass filters for the main speakers and low-pass filters for the sub output, but none of them specify a slope. I would guess these are all 12dB/octave since that's pretty much the norm for this level of headunit. When a deck has a higher slope such as 24dB/octave, they usually advertise that as a selling feature. This deck doesn't do that, so that's why I assume 12dB/octave. The sub's LPF is selectable between 55/85/120Hz, and the default setting is 120Hz. The HPF is fixed and no particular frequency is specified. For the HPF, I would assume 120Hz since that is the default for the sub's LPF. The slope is not specified, either in the owner's manual or the online specifications.

The true frequency of this subwoofer it 27-150 hertz. The 50-150 hertz is the crossover range for the subwoofer if you are using the normal input. However, if your receiver offers an LFE(low frequency effects) then you do not need to adjust that on the sub. The adjustment will be made on the reciever. In addition, I haven't found a movie or music signal that this sub won't pick up on the low end.

From 50Hz to 25kHz, suggest to have a sub woofer if you like to have more bass from your audio system.

Did you ever find an alternative to the BB2001? Funny, I just bought the im600 today, and it still had the slip in it for the BB2001. I would like to buy a subwoofer for it though, so let me know :) That goes for anybody reading this, too!

There is no access to the crossover. This is a very low budget piece of equipment. it's a low budget speaker in a box. The terminals aren't even decent.

"Good bass" is relative. In a small, sealed enclosure the reproduction from this is pretty well balanced between high and low frequencies. However, it cannot reproduce "deep" bass. An old but still valid rule-of-thumb is lowest LF response x highest HF response should = 500,000 to achieve a "balanced" sound. For ANY 4-inch driver the natural cut-off is around 5 kHz and I would say (without measuring it) it does go down to around 100 Hz = 500.000. So there you have it.

You need to stick with the same ohms. If you go with 4 or 6 ohm, you will transfer less power to the sub and it will sound bad.

Set the crossover on amp to HPF (high pass filter) and dial crossover to about 120hz

yes it will work, but you will not get the full effect of the sub. the concern should be with the amp's ohms that is being pushed threw the crossover. speakers only use what they are given. you will know it is working when the sound is clear. be sure that you have your polarities correct. at low volume it will sound clear and powerful, at higher volume keep it in the range where it sound clear,( this will keep it safe) . because it is clear it may be louder than you think. ...PS. if you want good compression have a shallow box for the woof, and for low resenence base have a deep box. i recommend having both for full effect, and use pine for the boxes yes it will work, but you will not get the full effect of the sub. the concern should be with the amp's ohms that is being pushed threw the crossover. speakers only use what they are given. you will know it is working when the sound is clear. be sure that you have your polarities correct. at low volume it will sound clear and powerful, at higher volume keep it in the range where it sound clear,( this will keep it safe) . because it is clear it may be louder than you think. ...PS. if you want good compression have a shallow box for the woof, and for low resenence base have a deep box. i... » Read More yes it will work, but you will not get the full effect of the sub. the concern should be with the amp's ohms that is being pushed threw the crossover. speakers only use what they are given. you will know it is working when the sound is clear. be sure that you have your polarities correct. at low volume it will sound clear and powerful, at higher volume keep it in the range where it sound clear,( this will keep it safe) . because it is clear it may be louder than you think. ...PS. if you want good compression have a shallow box for the woof, and for low resenence base have a deep box. i recommend having both for full effect, and use pine for the boxes « Show Less

Randall, para aire libre tienes que tener dos, son excelentes sub's y para instrumentos de frecuencias graves, responde muy bien, ahora yo tengo el sub P1800SX de vega, da mas rango de frecuncia que el 118XA, el 118xA da 36 Hz - 135 Hz y el P1800SX da 31,5 Hz - 272,0 Hz, para que lo tengas en cuenta.!

What's the frequency response of the mains? You will likely see the need to adjust the sub's high end slightly above the low end of the mains, using a cable into the l/r input jacks. Or you could use the crossovers in the receiver, set the speakers to small, crossover wherever you think the low end drops off on the mains... usually 10 hz above the listed specs. Then connect the sub the the lfe input, that bypasses the crossover in the sub.

I have measured their impedence as around 4 1/2 ohms over much of their frequency range; this is likely to rise around the crossover point when you add a capacitor (eg 3.3 microfarad) to keep low frequencies out. Whether they sound any good will depend on whether they are similar to what you are replacing, they are very efficient and might end up sounding very bright, with unpredictable integration with whatever woofers you are using. Good luck! Richard

The documentation for this item is appalling. I do not use a subwoofer. The Technical Specs can be found at:-http://store.sony.com/5.2-ch.-4k-a-v-receiver-zid27-STRDH550/cat-27-catid-ESP-Home-Theather-ElectronicsWhere It states:-Amplifier/Receiver Amplifier Features*4 Ohm/8 Ohm Switching : Yes (6 ohm)*Sub Woofer X' Over : 17 points (40 - 200 Hz) and Inputs and Outputs Audio Outputs*Pre Out (Subwoofer) : 2I am sorry I cannot help you more.

I believe it is 4.25 tuned to 37hz, with woofer displacement(depending on driver) it moves the tuning up to about 40hz. Some subs might like 40hz, but most 15"s want a bit lower than that for best performance. Also the port area is pretty small, if you front fire it and care about noise, you'll hear port noise from about 40hz through a little over 50hz.

Product description: 2K crossover point using the included capacitor. If you wish to cross it higher as a super tweeter, I'd suggest you contact Part's Express tech support for the correct capacitor. Cheers.
